Based on the results of this study, the application of enamel matrix derivative to denuded root surfaces receiving coronally advanced flaps significantly increased the percentage of root coverage compared to CAF without EMD. In addition, EMD application was accompanied by a significant increase in keratinized tissue 6 months after surgery.

Annual prevalence was significantly higher in whites and Mexican-Americans (compared with blacks), individuals 17-39 years of age, cigarette non-smokers, and those with recurrent herpes labialis history; while it was lower in males. Point prevalence was significantly higher in whites, Mexican-American, individuals 17-39 years of age, cigarette non-smokers, and males.

Two citrus limonoids, limonin and nomilin, were tested for their effects on the development of 7,12-dimethylbenz[a]anthracene (DMBA)-induced buccal pouch epidermoid carcinomas. Forty-five female Syrian hamsters were divided into three equal groups. The left buccal pouches of the animals in each group were pretreated topically with two applications of dimethylsulfoxide (DMSO) (group I), a 2.5% solution of limonin dissolved in DMSO (group II) or a 2.5% solution of nomilin dissolved in DMSO (group III). After this initial treatment, 11 hamsters from each group were selected. The left buccal pouches of these animals were painted 2 or 3 times weekly with a 0.5% solution of DMBA in mineral oil. On alternate days the pouches were painted with DMSO (I), the 2.5% solution of limonin (II) or the 2.5% solution of nomilin (III). The 12 remaining hamsters were used as controls and were painted with mineral oil and DMSO (I), mineral oil and the 2.5% solution of limonin (II), or mineral oil and the 2.5% solution of nomilin (III). After 15 weeks the hamsters were killed, the pouches were excised and the tumors were counted and measured. Tumors of variable size were common in the animals treated with DMBA. However, the animals receiving topical applications of limonin exhibited a 60% reduction in tumor burden. Further comparisons between groups I and II showed that this reduction in tumor burden was due to a 20% decrease in tumor number and a 50% decrease in tumor mass. The results for group III showed that nomilin was considerably less effective as an inhibitor of DMBA-induced neoplasia.
